What is the z-score of x = 4, if it is equal to the mean? How does a sample size affect the z-score? What z-score has 2.5% of the normal distribution below it? Which of the following z-score values represents the location farthest from the mean? - z = +1.00 - z = 2.00 -...
Does it matter if the z-score is positive or negative?Normal distributionsA normal distribution has two ways of identification: alignment of the line of symmetry to the mean value and the shape that appears to be like a bell or a mound. The Z-...
What does a z-score mean? The z-score can be positive or negative. The sign depends on whether the observation is above or below the mean. For instance, the z of +2 indicates that the raw score (data point) is two standard deviations above the mean, while a -1 signifies that it i...

A z-score tells you how many standard deviations from the mean your result is. You can use your knowledge of normal distributions (like the 68 95 and 99.7 rule) or the z-table to determine what percentage of the population will fall below or above your result. The z-score is calcul...
Often, you will run one of the pattern analysis tools, hoping that the z-score and p-value will indicate that you can reject the null hypothesis, because it would indicate that rather than a random pattern, your features (or the values associated with your features) exhibit statistically...
This is where a z-score comes in handy. Also known as a standard score, New York University professor Edward Altman developed the z-score in the late 1960s. Altman’s goal was to determine the likelihood of bankruptcy of publicly traded companies. In addition to being a credit-strength ...
A score below 1.8 means it's likely the company is headed for bankruptcy, while companies with scores above 3 are not likely to go bankrupt. Investors can use Altman Z-scores to determine whether they should buy or sell a stock if they're concerned about the company's underlying financial...
A z-score is a statistical measurement that describes a value's relationship to the mean of a group of values. It shows how far away (expressed in units of standard deviations) from the mean—either above or below—a value is situated. Z-scores can help traders gauge the volatility of ...
